Roman Numerals for Parallel Minor?

[dwest2419]

So in the key of C how I formed a chord progression like this I-IV-bvii so that would look like this right? Cmaj Fmaj and Bbmaj.

But what I wanted to know was I dont know the rest of the roman numerals for the rest of the parallel minor chords like in the key of C parallel minor what are the roman numerals for each chord?

Cmaj = I
Dmin = ii
Emin = iii
Fmaj = IV
Gmaj = V
Amin = vi
Bdim = vii

But what about C major's Parallel Minor relationship what are its roman numerals?

Cmin = ?
Ddim = ?
Ebmaj = ?
Fmin = ?
Gmin = ?
Abmaj = ?
Bbmaj = ?

Actually, the bvii should be bVII since it is a major chord. Bb =/= Bbm which would give you vii or if you prefer VIIm.

In terms of harmonizing scale degrees, the VII is diminished in a major key, but major in a minor key.

The parallel minor harmonizing sequence is as thus:

i-iio-III-iv-v-VI-VII
